NFSD: don't report compiled-out versions as present
commit 15ddb4aec54422ead137b03ea4e9b3f5db3f7cc2 upstream.
The /proc/fs/nfsd/versions file calls nfsd_vers() to check whether
the particular nfsd version is present/available. The problem is
that once I turn off e.g. NFSD-V4 this call returns -1 which is
true from the callers POV which is wrong.
The proposal is to report false in that case.
The bug has existed since 6658d3a7bbfd1768 "[PATCH] knfsd: remove
nfsd_versbits as intermediate storage for desired versions".
